‘We have indeed revealed this (Message) in the Night of Power: And what will explain to thee what the night of power is? The Night of Power is better than a thousand months. Therein come down the angels and the Spirit by Allah’s permission, on every errand: Peace!.This until the rise of morn!’ (Quran 97:1-5)

Narrated Abu Huraira: The Prophet (SAW) said, “Whoever fasted the month of Ramadan out of sincere Faith (i.e. belief) and hoping for a reward from Allah, then all his past sins will be forgiven, and whoever stood for the prayers in the night of Qadr out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven .”

” I heard the Messenger of Allaah (SWT) say: “Whilst I was sleeping two men came to me and took my by the arm and brought me to a cragged mountain. They said, ‘Climb up.’ I said, ‘I cannot.’ They said, ‘We will make it easy for you.’ So I climbed up until I was at the top of the mountain. Then I heard loud voices. I said, ‘What are these voices?’ They said, ‘This is the howling of the people of Hell.” Then I was taken until I saw people hanging by their hamstrings, with the sides of their mouths torn and blood pouring from their mouths.’ I said, ‘Who are these?’ He said, ‘These are people who broke their fast before it was time.’”

Allah’s Apostle said, “Fasting is a shield (or a screen or a shelter). So, the person observing fasting should avoid sexual relation with his wife and should not behave foolishly and impudently, and if somebody fights with him or abuses him, he should tell him twice, ‘I am fasting.” The Prophet added, “By Him in Whose Hands my soul is, the smell coming out from the mouth of a fasting person is better in the sight of Allah than the smell of musk. (Allah says about the fasting person), ‘He has left his food, drink and desires for My sake. The fast is for Me. So I will reward (the fasting person) for it and the reward of good deeds is multiplied ten times.”
